Anti-TAPBP antibodies are used in the immunodetection of the protein TAP binding protein. In humans, the canonical protein has a reported length of 448 amino acid residues and a mass of 47.6 kDa. Its subcellular localization is in the ER. Up to 4 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. TAPBP is reported to be involved in association of MHC class I with transporter associated with antigen processing (TAP) and in the assembly of MHC class I with peptide (peptide loading). Synonyms for this target antigen include TAPA, TPN, TPSN, tapasin, NGS-17, TAP binding protein (tapasin), TAP-associated protein, and NGS17. TAPBP gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of TAPBP antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
